getting started

[photonguy]

hi everybody, i need a little help getting started with my tomtom car kit for ipod. i put in an address with the keyboard and thats it for me - i can go no farther. what is the very next step? i can't get the keyboard off the screen and i see no done button. thanks for any help as i also find no instructions anywhere in the box or online. i reckon this is easy for most but i find nothing intuitive at all with this tomtom.
